14 claims;

This. invention relates generally to containers and is more particularlydirected. to a container composed. of fibrous materiaLadapted to beutilized asan original package in dispensing various kinds of goods, andthe. method of. producing the same.

As is well known, fiber containers of various forms are now availablefor marketing numerous products. However, in the distribution of manymaterials, especially those. that are subject to rapid deteriorationunless adequately protected against fluid penetration, the use of fibercon-.

tainers has been more or less limited, largely because of thefact thatheretofore it has notbeen possible toeconomically manufacture a fibercon.- tainer that is not only durably leak-proof and i111.- pervious tomoisture penetration,,which are most essential, but light in weight. andof av rugged construction. Manifestly, in. the marketing of 'manrproducts'whichare customarily put outin so-called. bullccontainers, thegross weight of.

the package and the capacity of the container to withstand. rough.handling in shipping are im portant factors. 7

Therefore, the primary object of thisinvention is to provide afibercontainerof a simple and economical construction, which is rugged andrelative'ly' light in. weight and effectively responds to therequirements. for p-ackaging those materials. in the marketing of which.containers that are leak-proof and impervious to fluid penetration. areessential; my container bein so constructed that it: is feasible tostorethe. packaged goods. for long period of time, without the constituent;material of! the container being detrimentally affected, with theresulting-leakage and deterioration of the contained product'as is ofcommonoccurrence: in the use of existing types of fiber containers.

important object of this invention is toprovidev a. container having aninner bag-lik receptacle of flexible material, in which the contained.product is packaged, and an outer rigid casing, including a, tubularSHBH-Of'bOdY portion,

the receptacle embodying an outer wall of resil iesnt material. andbeing adapted to be entered within. the shell in a collapsed orsemi-collapsed condition, for'expansioninto conforming engagementtherewith, the resilient material reacting tofrictionally adheI'BtOfithe shell wall for. locat-' ing. the:v receptacle in. an adjustedposition with the'shell' relative to the. ends thereof, and functioningto. maintain the stabilityof thepackage within the casing,...undershiftingload conditions.

a container having an inner receptacle and an outer protective casing asaforesaid, in which the shell or body portion of thecasing issealablebyend-formingmembers frictionally entered there- 6. in, the ends of theresilient outer wall of the I packaging receptacle, when. located withinthe shell functioninglas; internalshoulders for defining the dispositionof the end-forming members inwardly of the shell ends. with which theyare associated} other resilientelements. being .i'nterposable betweenthe end-forming members of the outer casing and the contiguous. endsurfaces of the inner receptacle-to cooperate with the resilient wall ofthe receptacle in stabilizing the 15 inner load and cushioning thereceptacle, inthe completion of the container. I

It is also animportant object of this invention to provide a fibercontainer, possessingthe characteristics and advantages hereinbeforesetforth,

which may be conveniently hermetically sealed by the packer of thecontained. product, for the subsequent removal of the contents inbulk,orby. dispensing them from the container in, such quantities as may, be.desired,.at the option of v the purveyor or'user of the product, as thecase may -be. To this end, my invention contemplates hermetic sealingmeans which may be readily applied. tothe outer casing shell andbodilyremoved therefrom in a replaceable condition, to admit of bulk: removalof the container contents, the sealingmeans embodying a rupturableareawi-th which a collapsible spout-forming element is associated, fordoling out the contents, where it is desired to maintain the sealotherwise intact, as

in dispensing the contained product in small amounts. 7

A further object ofm'y invention is to provide an all fiber containerincluding an outer casing having a tubular shell and end-forming membersinsertable therein of a composition and so assembled in the completionof the outer casing of the container that the entire structure isreinforced againstv bending forces, the end-forming elements 45, beinginterlocked with the wall. of the shell in cooperation. with. the endedges. of the resilient wall of. the inner receptacle, in afiui'd-prooijointure and highly resistant to separation" under constantand shifting. loads.

possessing the aforementioned advantages and characteristics and amethod of producing the same in a manner which. may; be expeditiouslypracticed, so that a. container conformin to my Anotherobjectof.invention. isztop'rovide: invention maybe. most economically manufac- Myinvention also comprehends a containertured and thereby provide for moreextensive use of fiber containers in those fields in which theemployment of existing types of fiber containers has been found to beimpracticable, because of their high cost, apart from their lack ofdependability under the conditions that prevail in commercia1 operationsinvolving the marketing of the packaged products. Also, as will beevident, by utilizing the inner resiliently supported receptacle, as apackage, in conjunction with the outer rigid protective casing, I amenabled to produce a much lighter construction than otherwise, withoutsacrificing strength or durability.

Other objects and advantages flowing from the practicing of my inventionwill become evident as the description proceeds.

In the accompanying drawings, I have shown a preferred form ofcontainer, conforming to my invention, as it may be produced by mysimple and economical method of manufacture.

In the drawings:

Figure, 1 is a vertical cross-sectional view of a container produced inaccordance with my invention, t

Figure 2 is a top plan view, partly in section, of the container shownin Figure 1, on the line 2-2 thereof.

Figure 3 is an elevational view, partly in sec tion, illustrative of themode of assembly of the inner repectacle in association with othercomponents of the container.

Figure 4 is' an enlarged fragment of Figure 3, partly in section.

Figure 5 is a fragmentary perspective of an end-liner section adaptedfor association with an end-forming member of the outer casing and theresilient wall of the inner receptacle; and

Figure 6 is a collective showing, in perspective and section, toillustrate the sequence of steps in the assembly of certain of thecontainer components. I

Referring now to the drawings in detail, in which like characters ofreference are employed to designate similar parts in the several views,10 indicates the shell or body-portion of the outer casing of thecontainer, which is of a tubular shape and produced from pressedchipboard, or other suitable material, in the appropriate length.Preferably, the chipboard, in the production of the shell I0, isspirally wound, the convolutions or windings forming each of theconstituent laminations mating in butt joints and being bonded by anappropriate adhesive to the convolutions upon which they are superposedto build up a wall section of the requisite thickness. Silicate of sodahas' been found to be a highly satisfactory agent for use in uniting thespiral windings, to produce a strong, rigid shell.

End-forming members H and I2, each of the so-called diaphragm type, areinsertable within the respective ends of the shell II), in thecompletion of the structure of the outer casing, as herein afterdescribed. Since both of these endforming members are identical instructure and mode of functioning, the description of one thereof, willsuffice for the purpose of this disclosure. Taking the end-formingmember I I, as an example, it will be observed that it embodies astepped marginal portion l3, formed by superimposed concentric discs Mand I5 of different diameters, composed of pressed fiber and cemeritedvtogether throughout the area of their opposed surfaces, the disc M ofmajor diameter having a circumferential area corresponding to that ofthe interior of the shell or body-portion II), in which it is adapted tobe seated, under axially applied pressure. If desired, the endformingmembers may embody an embedded layer of moisture-proof material, or maybe otherwise rendered impervious to moisture penetratio'n, though thisis not essential to the practicing of my invention as herein shown.

When the shell II] has been formed, it is ready for the reception of theinner package-forming receptacle of flexible material, having an outerand supplementally applied surface of resilient material, constitutingthe external wall of the receptacle. Preferably, the receptacle and theouter wall-forming material are independently produced and the resilientmaterial adhesively secured to the external surface of the receptacle,to produce a composite wall construction of unitary characteristics.

In the present showing, the inner receptacle takes the form of a paperbag, as indicated at [9, which is formed in the usual manner to embody aclosed end or bottom 19a. The bag is then positioned on a mandrel orotherwise supported in expanded condition, and a sheet of corrugatedpaper or light-weight paper board of a width less arable bond. Thelength of the corrugated sheet is such as to provide for the meeting ofthe opposed edges of the sheet in surrounding engagement with the bagwall, in a butt jointure, as indicated at IBb, or if preferred, they maymarginally overlap in the registration of mateable 0pposite endcorrugations, to provide a uniform wall thickness in th zone of jointure of the edges. The composite construction thus produced,

possesses a relatively thin flexible inner wallforming surface and anexternal wall-forming surface having resilient characteristics, impartedby the corrugations coacting with the web-portion lBa of theexternalwall-forming surface, with multiple advantages in the assembly and useof the container; as will become apparent.

The composite inner receptacle, including the bag I9 and the externalresilient wall l6, which hereinafter will be referred to simply as thereceptacle I9 forthe sake of brevity, except where specific reference isto be made to the external Wall and its functions, is inserted in'thetubular shell I 0, as shown in view A of Figure 6, in a collapsed orpartially collapsed condition, as illustrated in view B of said figure.The receptacle is then expanded by internally applied pressure, as bythe hands, in conformation with the inner wall of the shell in, as inview C of Figure 6, the hill surfaces of the corrugations of theexternal wall l6 of the receptacle frictionally adhering to the shellsurface, in the reaction of the corrugated material to thereceptacle-conforming step, The frictional pressure generated betweenthe external wall of the receptacle and the shell wall is suflicient tosupport the receptacle in suspension between the open ends of the shellID, in any.

The cross-sectional dimension of: the wall ofthe ring Zmobv-iously corresponds. to the width of' the ,baseof" thestepped edge l3of the end-forming member" it, so as to insure a tightfit and form a virtually her metic jointure between the end-closure andthe shell'or body portion l. I

For the loading process; the end member-- H and its: retaining ringfunction as the base of the assembly, the material to be packaged beingintroduced intothe receptacle tlrrough theth as i been loadedv to theappropriate level, the free portion of the wall is folded upon itself tothe levelof the contained material, with the sections forming the foldin: overlapping engagement, as-rat lab inFigure 1:, to form a continuousor uninterrupted end-forming surface, indicated at 2'90. The overlappingreceptacle sections, ifpreferred, may/ be: cemented together orotherwise sealed in association. to enhancexth'eintegrity of theclosure.

A second end linen I58: is now superimposed upon the'closedmouth; of thebag I 9, in the'man ner. previously" des lihfidi, with reference to theV Figure 4 opposed-tothe counter-pressure of the engaging disc of theend-member [2: which is ne'xtaenteredLin the-open end: of the-shell topress, the end liner l8. into close association with: the

.oppo'sed' surface of: the: bag and the opposed edge" of v thecorrugat'ed external wall [5 of the receptacle, the marginal portions ofthe two-end liners. l1 and 18 being deformed under pressure of theengaging end surfacesof the corrugated wall; of the receptacle, asindicated at" l 'l'b in and minor discs of the endemember' l2 andtherial, indicated at 2'3, cemented to the outer sur face of thesmaller'disc 15 of said member. A-

- collapsible spout-forming element 24', apprcpri ately' shaped; havingits base portion 24a, is cemented to the disc l5; in juxtaposition tosaid aperture said element" being scored along lines, as at 2412; forfolding; in the formation of the spout. As will be obvious, bysimultaneousl'ypuncturing the paper 23 and thebottom I90, of thebagandshaping the spout, the con-- tents may be poured from the container.aperture 22; isscalable thereafter as desired.

For theremoval of the" contents, with the receptacle intact, or forremoving the contents from; the receptacle in bulk, the split ring 26 isremovable by separating its overlapped ends to' strip it from itsfunctioning position in a contracting movement of thering out or engagement with the shell and end-member surfaces, to afford access to theinterior of the shell; .or the ring may bepri'ed upward out offunctioning' position, without separating its ends;

To facilitate; unseating of the endmember H;

a when theretaining ring has been removed, a

fiexibletab '25 is provided; one end of which isenteredbetween'the-discs Mand l5 of said memher, when they are cementedtogether, to virtually become unitary therewith, the free end of the tabbeing disposable above the ring 211 and the surrounding edge ofthe-shell, IS, in the sealing of the container, so that it may begrasped to unseat said end member in anupward dislocatin -movementManifestly; the tab may al'sobe used to simultaneously dislocate: boththe endimember- H and the retaining ring 211,, from containersealingposition, if desired; the mode of its use being optional; j

fn' u" of: d p n me so el upon the. f ictional engagement attirerespective 20 ant-1121, with the opposed and coactingsurfaces, of" the,end

members H- and i2 and the inner wall-of the As will be noted, especiallyfrom Figures 13,-3'1

and 4', the depth of the retaining rings 20, 2f,

end; liner Hi, for similarly: cooperating: with provides for theirprojection beyond the ends of the shell II with which they arerespectively associated, either ring thereby being adaptedto function asthe base element and to take the vertical load, as directly transmittedfrom the filled receptacle to the end-member with which the ring isassociated. Thus there is no possibility of movement of the end memberrelative to the shell, under load, with a resulting impairment of theend seal, as might occur were the ring positioned inwardly of the end ofthe shell, with the shell end serving as the supporting surface or base.

From the foregoing, it will be apparent that I have devised a simple andhighly eificient construction, in which the material packed within thereceptacle is amply protected against deimpervious .to moisturepenetration, the hermetic qualities of the seal that is afforded intheclosure of the receptacle being augmented by the manner in which theend members of pressure diaphragm properties are interlocked with thebody portion and engage the peripheral edges of the respective opposedcorrugated end liners, to conformingly press them into sealing position,as described. Obviously, the inner wall of the composite receptacle l9may be constituted of material suitable to the characteristics of thematerial to be packed therein. For example, in some instances, thereceptacle may be composed of Cellophane, while in others it may be ofpaper of the desired weight, waterproofed, or otherwise, or a fabricbag-like receptacle may be used, the protective resilient material l6being united thereto, as set forth. In some instances, as will beevident, the corrugated material l6 may be separate from the bag andindependently inserted in the shell in conforming engagement therewithand the bag then introduced into the expanded corrugated sheet anddilated to conform thereto, thecorrugated material thus functioning as aliner, interposed between the bag and the shell wall. Also, as will beevident, a lesser quantity of material than that for which a bag isdesigned may be packed therein and the container sealed as stated, thecorrugated external wall, as pointed out, providing for the location ofthe receptacle external the shell in properly spaced relation to theends thereof, for the insertion of the end-forming members, in theposition to which the receptacle may have been adjusted for the desiredloading, the top and bottom edges of 'the corrugated material, definingthe positions of the end-forming members of the outer casing relative tothe respective ends of th closed inner receptacle. When desired, as willbe clear from the disclosure, the contents of the container may beextracted conjointly with the removal of the receptacle therefrom inpackaged condition, as set forth, when the nature of the product permitsof this procedure. Thus a container is rendered reusable, merely byinserting another receptacle in the outer casin assembly and rescalingit with the removed end-member and retaining ring or newcounterpartsinstalled, in the manner described, following thereceptacle-fillingoperation.

While I have described, my inventionmore or less specifically, withreference to the'embodiment shown, it will be understood that it maytake other forms, as to structural details; also that the sequence ofthe steps of assembly and loading may be varied, to suit convenience inthe production and packaging operations, within the spirit and scope ofthis disclosure.
